Are most preist gay

As you know, Catholic Priests are not allowed to marry. As part of the "vetting" process for suitability for priesthood, nuns interview prospective priests to decide if they are suited to a celebate life.

The result of this is that the nuns were inclined to select gay priests as they were, obviously, very unlikely to want to get married. As a result, it has been estimated that 30% of Catholic priests are gay - although that figure is pretty much an educated guess.
